1. A mechanical seal device (1) with a mechanical seal (10), which comprises a dry-running protection device (20), the dry-running protection device (20) having at least one microsystem (21) which outputs a digital measured value (W) being a temperature value, the microsystem (21) having:
a temperature sensor (22),
a wireless data interface for outputting the digital measured value (W), and
a micro constructed power generator,
the microsystem (21) further comprising a circuit board (27) and an MEMS chip (26), the MEMS chip (26) being arranged on a circuit board (27), the MEMS chip (26) comprising the temperature sensor (22) for determining the measured value (W), the wireless data interface sharing the circuit board (27) with the temperature sensor (22),
the microsystem (21) with the temperature sensor (22), the wireless data interface, and micro constructed power generator, the MEMS chip (26), and the circuit board being arranged on and/or in the mechanical seal (10), wherein the microsystem is assigned to a sliding ring (11) or a counter ring (12) of the mechanical seal (10) and wherein the assignment is an arrangement of the microsystem (21):
a) on and/or in the sliding ring (11); or
b) on and/or in the counter ring (12).
